7. The method according to claim 4 , which comprises transmitting messages to and from at least one of the first and second telecommunications terminal using WAP protocols or Hypertext Transfer Protocol.
8. The method according to claim 1 , wherein the step of determining the profile relating to the capabilities of the first telecommunications terminal comprises sending a query to a database of the telecommunications network wherein the terminal device characteristics are stored.
9. The method according to claim 1 , which comprises determining the profile relating to the capabilities of the first telecommunications terminal by sending a query to the first telecommunications terminal.
10. The method according to claim 1 , wherein the address contained in the reference includes a URL.
11. The method according to claim 1 , wherein the encrypted user data object to be transmitted is also transmitted to the data provisioning component in addition in the request of the switching component to the data provisioning component.
12. The method according to claim 1 , wherein, if the result of the check by the data provisioning component is negative, the information to the switching component contains a pointer to the data provisioning component from which the switching component can request a different usable user data object in accordance with the profile of the first telecommunications terminals.
13. The method according to claim 1 , wherein, if the result of the check by the data provisioning component is negative, the information to the switching component contains a different usable user data object.
14. The method according to claim 1 , wherein the first telecommunications terminal, in response to the notification of the switching component concerning the provision of a usable encrypted user data object, transmits a request for the usable encrypted user data object to be sent to the switching component, and the switching component thereupon sends the usable encrypted user data object to the first telecommunications terminal.
15. The method according to claim 1 , wherein the first telecommunications terminal is part of a first telecommunications network.
16. The method according to claim 15 , wherein the first telecommunications network is a mobile radio network.
17. The method according to claim 16 , wherein the first telecommunications network operates in GSM or UMTS standard.
18. The method according to claim 15 , wherein the switching component forms a part of a second telecommunications network that is connected to the first telecommunications network.
19. The method according to claim 18 , wherein the second telecommunications network is a telecommunications network based on Internet protocols.
20. The method according to claim 19 , wherein the second telecommunications network is a telecommunications network based on Hypertext Transfer Protocol.
21. The method according to claim 19 , wherein the first and second telecommunications networks are connected to one another by way of a WAP gateway.
22. The method according to claim 1 , which comprises, following receipt of the encrypted user data object, transmitting a rights object containing a key and usage rights for the received encrypted user data object.
23. The method according to claim 1 , wherein the data provisioning component is a server of a content provider.
24. The method according to claim 1 , wherein the user data object contains text information, audio information, video information, an executable program, a software module, or a combination thereof.
